Stars campaign until they are blue in face

Trends come and go, but this summer sees the birth of a new fad: blue faces. The startling look, to be sported at Glastonbury by some of the festival's best-known performers, is part of an Oxfam climate change campaign.

Those appearing include Jarvis Cocker, Fatboy Slim (Norman Cook), Luke Pritchard of The Kooks and singer VV Brown. "I'm sure people will have a great time being inventive about what they should paint," said Cook. Oxfam plans to campaign over the next six months for a fairer climate deal.
